Thirty patients completed this open-label, multicenter prospective study performed to evaluate the efficacy and safety of terbinafine treatment of onychomycosis of the feet in elderly patients. Inclusion criteria included an age of 60 years or older, a diagnosis of onychomycosis confirmed by positive potassium hydroxide (KOH) preparation at baseline, and toenails capable of regrowth. Patients were excluded from the study if they had received any systemic antifungal therapy within the previous 3 months or topical antifungal therapy within 1 week prior to the start of the study; had psoriasis; had toenail abnormalities interfering with normal toenail appearance; were immunosuppressed or immunodeficient; or had serum hepatic enzyme (serum glutamic-oxaloacetic transaminase, SGOT; serum glutamic-pyruvic transaminase, SGPT) values greater than 1.5 times the upper limit of normal at baseline. Following baseline evaluations, eligible patients received a 12-week supply of oral terbinafine (250 mg/day) for self-administration. Compliance was assessed by tablet counts at each visit and defined as the use of at least 80% of the medication prescribed at the first two visits. Follow-up evaluations were conducted for the next 60 weeks, for a total study period of 72 weeks. These visits occurred at weeks 6, 12, 24, 36, 48, and 72. All follow-up visits included: (i) the reporting of adverse effects; (ii) assessment of efficacy by KOH preparation, mycologic culture, and investigator evaluation; and (iii) physician and patient global assessments of various quality of life parameters (except for the visit at week 36). Safety and tolerance were assessed by physical examination at baseline and week 12, by laboratory evaluations (hematology, blood chemistry, and urinalysis) at baseline, week 6 and week 12, and by reporting and evaluation of adverse events throughout the entire study. Investigators assessed the extent of involvement of the target toenail and recorded global assessments of therapeutic efficacy at all visits. Mycologic evaluation was conducted by KOH preparation and a mycologic culture of the target toenail. Because of discrepancies in KOH results between the investigator sites and the central laboratory in early analyses, we chose to use the mycologic culture results to evaluate efficacy. Because all 30 subjects were treated with terbinafine, the entire group was considered for safety evaluation.

Introduction. Terbinafine is reported to be associated with rhabdomyolysis. We present a patient taking terbinafine who may have developed exercise-induced rhabdomyolysis. Case Report. A healthy 40-year-old female developed onychomycosis of the right first toe for which she was taking terbinafine. After an increase in her exercise regimen, she began experiencing notable myalgias of the triceps. During outpatient evaluation, the patient was found to have elevated and worsening creatine kinase (CK) and aspartate transaminase. At evaluation in the emergency department, CK was <5000 IU/L and had decreased. She did not have electrolyte abnormalities, kidney injury or kidney failure. Discussion. Patients may be at risk for exercise-induced rhabdomyolysis while on terbinafine and may need to be cautioned regarding the intensity of exercise.
